Venous blood
Returning to the heart faster can also increase the blood flow rate of the leg veins.
The faster the venous blood returns, the more blood is injected into the heart every time it beats, which makes the athletes passively maintain a high intensity state, as if everything is logical.
However, the experimental data does not support this statement. In some studies, experienced marathon runners are usually selected, and the experimental distance is usually controlled within 15Km.
After the experiment, quite a few marathon runners didn't feel as tired as when they didn't wear compression socks, so the debate about whether compression socks can improve their running performance has been going on.

University researchers found that compression socks did increase the blood flow of lower limbs and reduce the heart rate during high-intensity endurance exercise, but this study also found that even so, compression socks did not improve the running performance of the subjects.
Other studies have also found that compression socks can not improve the performance of 10 km running.
